he “ found the young bugs all hatched, and clustered under 
their mother amongst the empty egg-shells; they were 
yellowish-green in colour, their thoraces becoming darker 
than their abdomens;” and he “saw them moving their 
antenne,” On 3rd July he “found them showing a red 
streak down the middle of the abdomen, and on the 6th 
they had moved away from the egg-shells, and were 
got together by themselves.” On the 9th he “ found them 
moulting, and saw some of them kicking away their cast 
skins behind them: their colours were bright at first, 
yellow with vermilion stripe, and they soon began to move 
about more freely, and on the 13th migrated, now with 
sadly diminished numbers, to a neighbouring catkin.”’ 
Mr. Hellins says that he then despatched the mother, with 
eight young ones, to Mr. Douglas, and I believe I have some 
of the actual specimens now before me; they are, of course, 
a good deal shrivelled up and are scarcely more than 1 mm, 
in length; the rostrum projects considerably beyond the 
apex of the abdomen, and the mandibles and palpi are 
projected in front. Whether this has been done artificially 
or whether in the young state these are free from the rostrum 
Tam unable to say. I am not aware that similar habits to 
those given above have been noticed in any other genus or 
even species.
